TROUBLE SHOOTING
AIR FILTER
• Accumulated dust in the air filter will
reduce engine efficiency. Increase fuel
consumption and allow abrasive particles
to pass into the engine. Remove the air filter
as often as necessary to maintain in a clean
condition.
• Light surface dust can readily be removed
by tapping the filter. Heavy deposits should
be washed out in suitable solvent.
• Remove filter cover by loosening air filter
cover knob.
ADJUSTING CARBURETOR
NOTE
Do not adjust carburetor unless necessary.
If you have trouble with the carburetor, see
your dealer. Improper adjustment may cause
engine damage and void warranty.
FUEL FILTER
• Fuel tank is fitted with a filter.
Filter is situated at the free end of fuel pipe
and can be picked out through fuel port with
a piece of hooked wire or the like.
• Check the fuel filter periodically. Do not
allow dust to enter into fuel tank. Clogged
filter will cause difficulty in starting engine or
abnormalities in engine performance.
• When filter is dirty, replace the filter.
• When the inside of the fuel tank is dirty, it
can be cleaned by rinsing the tank out with
gasoline.
CHECK SPARK PLUG
• Do not attempt to remove the plug from
a hot engine in order to avoid possible
damage to the threads.
• That the fuel system is in good condition
and fuel is flowing to the engine.
• The ignition system is in good condition and
the spark plug, sparks correctly.
• Compression of the engine is adequate.
FAILURE TO START
• Dispose of fuel in tank.
• Insure that fuel is fresh and clean.
• Check fuel filter to make sure it is clean.
(Replace filter if necessary).
• Make sure air filter elements are clean.
• Install new, properly gapped spark plug.
• When there is serious trouble with the unit,
do not try to repair it yourself, but have your
distributor or dealer do it for you.
